Do autotrophs need to carry out cellular respiration? Why or why not?
Answer:
Yes, autotrophs need to carry out cellular respiration.
Explanation:
Autotrophs make their own food. ... Many autotrophs make food through the process of photosynthesis, in which light energy from the sun is changed to chemical energy that is stored in glucose. All organisms use cellular respiration to break down glucose, release its energy.

When scientists carefully measure the lichens and agree on their thickness and how often they appear which parts of the scientific cycle are scientists using
Answer:
This question is incomplete; the complete question including the options are as follows:
During a study of lichens and air quality in part of China, scientists measure the thickness of lichens and estimate how many rocks and trees are covered with lichens in one town. The scientists are following the scientific cycle of observing while using a systematic process, establishing facts, explaining facts, and then returning to the systematic process to collect more facts.
When scientists carefully measure the lichens and agree on their average thickness and how often they appear, which parts of the scientific cycle are the scientists using?
A- process and facts, because they are using a systematic method to measure and then record data
B- process and facts, because they are observing lichens and air quality and describing why they are related
C- explanation and process, because they are using a systematic method to measure and then record data
D- explanation and process, because they are observing lichens and air quality and describing why they are related
The answer is A. process and facts, because they are using a systematic method to measure and then record data
Explanation:
Scientific experiments follow a series of well coordinated steps. These steps range from making observations to analyzing data. In this experiment, which involves scientists conducting a study of lichens and air quality in a part of China, a scientific cycle is being followed.
However, the scientists get to a point where they carefully measure the lichens and agree on their average thickness and how often they appear. This point is where the ANALYSIS OF DATA in the experiment occurs. Therefore, the part of the scientific cycle they are using is PROCESS and FACTS, because they are using a systematic method to measure and then record data.

Which of the following is NOT true of saturated and unsaturated fats? A. Saturated fats are saturated with hydrogen while unsaturated fats are not because they do not have electrons available to bond with hydrogen. B. Saturated fats can pack more tightly and form solids at room temperature while unsaturated fats are liquid at room temperature. C. Saturated fats, because they lack double bonds between their carbon atoms, stay liquid at room temperature while unsaturated fats form solids.
Answer:
Saturated fats can pack more tightly and form solids at room temperature while unsaturated fats are liquid at room temperature.
The statement which is NOT true about saturated and unsaturated fats is Choice C: Saturated fats, because they lack double bonds between their carbon atoms, stay liquid at room temperature while unsaturated fats form solids.
Generally, fats are classified as either Saturated or Unsaturated fats.
Saturated fats are fats which are saturated with hydrogen, and consequently have only single C-C bonds.Contrarily, unsaturated fats are not saturated because they lack available electrons to bond with hydrogen and consequently, have double bonds between successive Carbon atoms in their structure.As a result of the statements above;
Saturated fats can pack more tightly and form solids at room temperature while unsaturated fats are liquid at room temperature.Inference from the statements above therefore suggests that the statement which is not true is Choice C: Saturated fats, because they lack double bonds between their carbon atoms, stay liquid at room temperature while unsaturated fats form solids.

ANSWER FAST PLEASE According to Dalton’s theory, why are carbon and oxygen differ.ent elements?
According to the Dalton's theory, carbon and oxygen are different elements because they are made up of different atoms which have different numbers of proton and neutrons.
What is Dalton's theory?John Dalton proposed his modern theory of atoms in 1803. He discovered atom, which is the smallest unit of particle. This theory is also known as the atomic theory of matter.
In this theory, he stated that every single atom of an element, such as sodium, is same as the other atoms of the same element. He also stated that the atoms of one element differ from the atoms of other elements. This theory is mostly found to be true. For example: A sodium atom is different from a carbon atom.
However, his theory was found to be found as the atoms present in the elements are found to be divisible into even smaller particles like protons, neutrons, and electrons.

As seen from Earth, what causes the Moon to change its apparent shape throughout the month?
Answer:
The Moon doesn't emit (give off) light itself, the 'moonlight' we see is actually the Sun's light reflected off the lunar surface. So, as the Moon orbits the Earth, the Sun lights up different parts of it, making it seem as if the Moon is changing shape.

Quantitative data measures categories like color or movie genre.
True
False
Answer:
[tex]\boxed {\tt False}[/tex]
Explanation:
First, let's define quantitative data.
Quantitative data is
Data that can be expressed as a number or a quantity. This type of data can be measured, for example: length, temperature, time, etc.There is also another kind of data, called qualitative data.
Qualitative data is
Data that is expressed with descriptions. This type of data is observed. Examples include: colors, smells, tastes, etc.We are asked about color and movie genre. This can't be measured or expressed as a number, so it is not quantitative data. Instead, it is qualitative data.
